The ordinary door stop is simply a wooden knob with rubber tip, or ring, that may be fastened to the floor or a baseboard, and is usually made up in the forms shown in [Fig. 103]. Better grades made of iron or bronze are also available. These come in various shapes, as shown in [Fig. 104]. Frequently, as shown at a, a hook for fastening the door in an open position is combined with the door stop.

The door stop with the hook holdback is not always convenient to use, so that the automatic holdback, or door holder shown in [Fig. 105] is sometimes employed. This holder can be disengaged by a pull on the handle of the door and automatically catches the door in an entire open position.
Where it is desired to hold a door in any position or to release it quickly, the rubber-tipped holder shown in [Fig. 106] should be used; this device is easily operated and controlled by the foot.
